Be it known that l, RAY l3. JACKSON? a. citizen of the United States, and a resident of'EdgeWood Park, in the county of Selle "5 gheny and State of Pennsylvania, have invented anew and useful Improvement Suspension Devices, of Which the follow is a specification.

My invention relates to suspension de- 10 vices and particularly to suspension devices for insulators that are used in high-potential electric circuitsn One object of my invention is to provid a suspension device of the LbOYQ-lIXllBFLl-QQ led separated Without the use of tools.

A further object of my invention is to provide a suspension device or coupler of the above specified class that shall l ga'gement and that shall, While in loo relation, permit of considerable rela 0 movement or play between the interlockm members thereof.

conical portion 5 having external corrugat ons 6 andan lnternal corrugated recess 4.

Each of the connectiiin devices 3 and is also provided with an internally-co upwardly-projecting portion 5 and i cured thereto by cement 9 or other e material. Each connecting device also provided with a rod member 10, the upper end of which is secured Within the 7 of anadjacent insulator unit r suitable cementing material ii.

outwardly-projecting socket members to enand a downwardly-projecting ridge portion to engage said grooved portion.

4. A suspension devicecomprising two cooperating and separable members, one of which has a plurality of socket portions and the other of which has corresponding lugs to engage said socket portions,

one of said members also having rigid pr01ect1ons to cooperate with a recess in the other member,

5. The combination with a plurality of spaced insulator units, of connectors extend .ing therebetween that severally comprise two cooperating and separable members,'one

of which has a plurality of socket portions and the other of which has corresponding lugs to engage said socket portions, one of ingtoward the other but sesame said members being also provided with rigid projections to cooperate with a recess in the other member.

6. A suspension device comprising two separable interlocking members one of said members having a lug portion and the other a socket portion adapted to engage said lug portiom and means comprising a rigid projecting portion on one of said members and a recessed portion on the other of said members for preventing the accidental disengagement of the lug and socket portions.

7. A suspension device comprising a retaining member having a. longitudinal recessed ridge on a surface thereof, aplurality of portions projecting from the plane of said surface at opposite sides or said ridge, a lug on each of said projecting portions projectspaced therefrom, a suspension member disposed between the ends of said lugs, socket portions on said suspension member to cooperate with said lugs and portions extending in the direction of said ridge from said suspension member, the latter of said portions being normally out of said recess but of such relation thereto as to prevent accidental disconnection of vsaid suspension member from said retaining member.

in testimony whereof i have hereunto subscribed rny-na ne this th day oi Nov., 1915.
